DETAILED DESCRIPTION OF THE INVENTION

a. Outline of Playing Method

FIG. 1 is a flow chart illustrating a method of playing a game according to a first embodiment of the invention. The method of playing a game according to the present embodiment relates to a kind of poker game that performs a win game. The win game uses a plurality of kinds of cards and allows a player to exchange a card selected by the player from a plurality of cards distributed initially with another card. When the player wins the game with a plurality of cards finally distributed that matches a predetermined combination, the player receives a predetermined award. In the above win game, the playing method first judges whether a card combination entitled to an award is a specified combination such as a Flush of Hearts or Diamonds (step S1). If so, the playing method performs a special game which determines a gaming condition of a high-probability win game supplied in the next game (step S2). Then, the playing method supplies a plurality of decks (bundles of cards for playing games, in particular sets of 53 playing cards) in accordance with the result of the special game, and performs win games repeatedly until a winning outcome is achieved in any one of the decks supplied. That is to say, the playing method performs a high-probability win game having a higher probability of winning outcomes by supplying a plurality of decks to the player.

b. Configuration of Poker Machine

The general view of a gaming machine in the first embodiment of the invention is shown in FIG. 2. The present invention is described below by taking as an example a poker machine, which is suitably applicable to the gaming machine according to the present invention.

Specifically, the present embodiment relates to the poker machine using medals. However, the gaming machine of the present invention may be a gaming machine using, as a playing medium, coins, medals, tokens, or cards storing playing value information.

A first display 32 is disposed on the front of a poker machine 10. A second display 33 is disposed above the first display 32 on the front of the poker machine 10. The first display 32 displays cards distributed to a player, and an award table showing card combinations corresponding to any award. The second display 33 displays images of rendered effects. The first and second displays 32 and 33 are liquid crystal displays of touch-panel type.

A medal slot 63 is disposed in the vicinity to the right on the front of the poker machine 10, and a medal payout opening 61 and a medal receiving pan 67 are disposed below the front. The player's medal insertion into the medal slot 63 enables gaming. Based on the game result, medals are paid out from the medal payout opening 61, and stored in the medal receiving pan 67. As is described later, a medal detecting sensor 31 (refer to FIG. 3) is housed inside the gaming machine where the medal slot 63 is disposed. The medal detecting sensor 31 detects insertion of medals by the player into the poker machine 10.

Decorative lamps 36 a and 36 b are disposed on the opposite sides of the poker machine 10, respectively. Speakers 46 a and 46 b are disposed in upper sections of the poker machine 10. The speakers 46 a and 46 b generate sounds effects, etc. in response to the game progress.

Various switches used for advancing a game are arranged below the first display 32.

A bet max switch 26 and a bet one switch 28 are used when the player starts the game. The bet one switch 28 increases the number of medals used for the game depending on the number of times the switch is pressed. The bet max switch 26 is used to bet five medals, namely the maximum number of medals, at a time.

A deal switch 24 and a cash out switch 22 are disposed on the left of the bet max switch 26. Five hold switches 20 are arranged above the bet max switch 26. The deal switch 24 is used when the player requests a display of cards. The player's operations of inserting medal(s) and pressing the deal switch 24 enable the images of distributed cards and new exchanged cards to be displayed on the first display 32.

The cash out switch 22 is used to pay out medals stored (hereinafter referred to as credited) in the poker machine 10. When the player activates the cash out switch 22 by a pressing operation, medals are paid out to the medal receiving pan 67.

The total number of the hold switches 20 is five. The hold switches 20 are arranged so as to correspond to the card images displayed on the first display 32, respectively. The hold switches 20 are used when the player selects a card to remain without being exchanged, after the cards are displayed. When the player activates by pressing the hold switch 20 underlying the selected card in the five cards displayed on the first display 32, the selected card remains unexchanged.

c. Configuration of Controller of Poker Machine

A control circuit of the poker machine as the present embodiment of the invention is shown in the block diagram of FIG. 3.

A main control circuit 60 as a controller is configured by connecting, through an input/output bus 64, a central processing unit (hereinafter referred to as a CPU) 66, read only memory (hereinafter referred to as ROM) 68, random access memory (hereinafter referred to as RAM) 70, a random number generator 65, and interface circuit groups 62 and 72 to each other. The input/output bus 64 inputs and outputs data signals, control signals or address signals to the CPU 66.

Based on a computer program stored in the ROM 68, the CPU 66 reads and writes data with respect to elements and units connected to the input/output bus 64, and cooperates with these elements and units to perform various types of processing. A timer (not shown) to be described later is housed within the CPU 66.

The medal detecting sensor 31 is connected to the interface circuit group 62 of the main control circuit 60. A detection signal from the medal detecting sensor 31 is converted to a predetermined signal by the interface circuit group 62, and then supplied to the input/output bus 64.

The deal switch 24 is also connected to the interface circuit group 62. The deal switch 24 transmits to the interface circuit group 62 a signal indicating an activation of the deal switch 24 by the player through a pressing operation, and this signal is then supplied to the input/output bus 64.

The hold switches 20, the cash out switch 22, the bet max switch 26 and the bet one switch 28 are also connected to the interface circuit group 62. When these switches are activated by the player's pressing operation, they transmit the corresponding signals indicating a pressing operation to the interface circuit group 62. These detection signals are then supplied to the input/output bus 64.

The speakers 46 (46 a and 46 b) and the decorative lamps 36 (36 a and 36 b) are also connected to the interface circuit group 72. The interface circuit group 72 controls each of the abovementioned units by supplying a drive signal and drive power, in accordance with calculation processing performed in the CPU 66.

The ROM 68 and the RAM 70, each serving as a storage means, are also connected to the input/output bus 64. The ROM 68 stores a control program for controlling the entire flow of the game in the poker machine 10. The ROM 68 also stores the initial data for executing the control program, a program for controlling flash operation patterns of the decorative lamps 36 (36 a and 36 b (refer to FIG. 2)) housed within the poker machine 10, and a program for controlling display on the first display 32. The ROM 68 further stores, for example, a plurality of kinds of lottery tables for associating a random number sampled by the random number generator 65, with a card image to be displayed on the first display 32, and a combination judgment table for judging if a combination of patterns represented in a plurality of card images displayed on the first display 32 matches a specified combination. The plurality of lottery tables has different probabilities of winning outcomes. When a certain specified combination occurs, the CPU 66 sets a table for a high-probability win game having a higher probability of winning outcomes than a normal lottery table, as a lottery table for an internal lottery (refer to FIG. 6). The RAM 70 stores the value of a gaming condition counter which indicates values of flags and variables used in the abovementioned program, a value of a high-probability flag indicating the state for executing a high-probability win game (in the present embodiment, 1 indicates the state for executing and 0 indicates the state for not executing), an initial value determined by the result of the special game indicating the number of decks to be displayed in the high-probability win game, a value of a gaming condition counter obtained by subtracting the number of decks specified by the player from the abovementioned initial value.

The random number generator 65 for generating random numbers is connected to the input/output bus 64. When an instruction for generating random numbers is transmitted from the CPU 66 to the random number generator 65, the random number generator 65 generates random numbers in a predetermined range, and transmits signals indicating the random numbers to the input/output bus 64. Based on the random numbers generated, the CPU 66 performs an internal lottery processing described later. The random numbers generated from the random number generator 65 are stored in the RAM 70.

In the present embodiment, the random number generator 65 connected via the input/output bus 64 to the CPU 66 samples the random numbers by way of example and without limitation. Alternatively, random number sampling may be executed under an operational program of the CPU 66. In this case, the random number generator 65 can be omitted.

A display and input controller 200 is also connected to the interface circuit group 72. Upon receiving an instruction for displaying an image sent from the main control circuit 60, the display and input controller 200 transmits drive signals indicative of driving the first display 32 and the second display 33, which are connected to the display and input controller 200. The display and input controller 200 also supplies signals, which indicate reception of an input to the touch-panel type select switches provided on the first and second displays 32 and 33, to the interface circuit group 72. The signals are then transmitted to the CPU 66 via the input/output bus 64.

A hopper controller 210 is also connected to the interface circuit group 72. Upon receiving an instruction for paying out medals sent from the main control circuit 60, the hopper controller 210 transmits a drive signal for driving a hopper 50 connected to the hopper controller 210.

d. Operations of Poker Machine

A main routine for controlling the poker machine 10, which is executed on the main control circuit 60, is shown in the flow chart of FIG. 4, and subroutines in the main routine are shown in the flow charts of FIGS. 5 to 11.

In the following, it is assumed that the poker machine 10 is activated in advance, and performs normal operation in a state in which the abovementioned random numbers used in the CPU 66 are initialized to predetermined values.

First, as shown in FIG. 4, the CPU 66 performs bet processing (step S11).

In this processing, in response to the player's medal insertion, pressing the bet max switch 26 or pressing the bet one switch 28, the CPU 66 performs respective bet processing, accordingly. The details of the bet processing are described later. When the bet processing is terminated, the CPU 66 advances the processing to step S12.

In step S12, the CPU 66 performs the internal lottery and executes processing for extracting a card. In this processing, the CPU 66 transmits an instruction for generating random numbers to the random number generator 65. Upon receipt of this instruction, the random number generator 65 samples random numbers. The random numbers generated by the random number generator 65 are then stored in the PAM 70 as random numbers indicating a lottery result. The CPU 66 refers to the lottery tables and determines the kinds of cards corresponding to the random numbers. The CPU 66 then stores the data of the kinds of the cards in the RAM 70. The details of the internal lottery processing are described later. When the internal lottery is terminated, the CPU 66 advances the processing to step S13.

In step S13, the CPU 66 performs processing for displaying a card. The CPU 66 supplies the data of five cards to be initially distributed by way of display to the player from the cards determined by the internal lottery in step S12, and an instruction for displaying a card image to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the corresponding image data and stores the data in a video RAM housed in the display and input controller 200. In this way, the first display 32 displays the five cards initially distributed to the player. When the high-probability win game is executed, a plurality of five-card sets is displayed on the second display 33. The details of the card display processing are described later. When the processing for displaying a card is terminated, the CPU 66 advances the processing to step S14.

In step S14, the CPU 66 performs processing for exchanging a card. In this processing, the CPU 66 causes the first display 32 to display new card images thereon, in response to the player's card exchange operation. Before displaying the new card images, the CPU 66 judges whether the patterns of the five cards to be displayed after an exchange match a certain specified combination. Based on the judgment result, the CPU 66 changes a card display sequence. The details of this processing are described later. When the processing for exchanging a card is terminated, the CPU 66 advances the processing to step S15.

In step S15, the CPU 66 judges whether the patterns of the five cards displayed on the first display 32 after the exchange match a card combination entitled to an award (for example, Two Pair, Three of a Kind, Flush, etc.). The judgment is made referring to the combination judgment tables stored in the RAM 70. In the abovementioned processing for displaying a card, in order to change the card display sequence, the CPU 66 has already judged whether the patterns of the five cards to be displayed after the exchange match the specified combination, before the cards are displayed. However, if the judgment in the above processing in step S14 is made only with regard to the specified combination used for controlling the card display sequence, the CPU 66 performs another judgment in processing for judging a result in step S15. Namely, the CPU 66 determines which card combination entitled to an award is matched by a combination of patterns of the cards displayed after the exchange. In contrast, when the CPU 66 has performed judgment for not only the specified combination, but also all of the card combinations entitled to an award in the processing for exchanging a card in step S14, it may be possible to use the judgment in step S14 without performing any new judgment in the present step S15. The details of this processing are described later. When the processing for judging a result is terminated, the CPU 66 advances the processing to step S16.

In step S16, the CPU 66 performs processing to judge whether a game is in the high probability mode. If the CPU 66 finds a high-probability win game based on the value of a high-probability flag stored in the RAM 70 (namely, the value of the high-probability flag is 1), the CPU 66 advances the processing to step S17. Otherwise, (namely, the value of the high-probability flag is 0), the CPU 66 advances the processing to step S19.

In step S17, the CPU 66 performs processing to judge whether a predetermined combination is present. If so, CPU 66 advances the processing to step S19. If not, CPU 66 advances the processing to step S18.

In step S18, the CPU 66 performs processing to judge whether a value of a gaming condition counter is 0. If the value of a gaming condition counter stored in the RAM 70 is 0, CPU 66 advances the processing to step S19. If not, CPU 66 advances the processing to step S14.

In step S19, the CPU 66 performs processing for providing rendered effects and paying out. The CPU 66 performs this processing in accordance with the judgment result in step S15. Specifically, when the CPU 66 determines matching of a predetermined card combination entitled to an award, the CPU 66 causes the first display 32 to display the predetermined card combination, and also causes the number of medals obtained by the player to be added to the number of credits in accordance with the number of decks played. When the number of credits exceeds 50, the exceeding number of medals is paid out through the medal payout opening 61 to the medal receiving pan 67. On the other hand, when the judgment result is the absence of any card combination matching an award, the CPU 66 causes the first display 32 to display notification of the absence of any winning card combination. When the CPU 66 finishes the processing for providing rendered effects and paying out, it terminates the main routine.

e. Bet Processing

In step S11 (FIG. 4), a bet processing subroutine shown in FIG. 5 is called.

Firstly, the CPU 66 performs processing to judge whether medals have been inserted, or the bet switch has been activated (step S21).

In this processing, the CPU 66 determines whether it has received one of the following signals: a signal indicating an insertion of medals into the medal slot 63 sent from the detecting sensor 31, a signal indicating activation of the bet max switch 26, and a signal indicating activation of the bet one switch 28. If the CPU 66 determines the reception of one of the signals, it advances the processing to step S22. Otherwise, the CPU 66 repeats step S21.

In step S22, the CPU 66 performs processing for adding a bet number. In this processing, the CPU 66 adds the number of credits in accordance with the result in step S21. That is, the CPU 66 stores as a bet number, in the RAM 70, the sum of the number of detections of medal insertion and the number of times the bet one switch 28 has been activated. The maximum bet number is “5”. When the bet max switch 26 is activated, the maximum value of “5” is stored in the RAM 70, irrespective of the number of detections of medal insertion and the number of times the bet one switch 28 has been activated. When the bet number addition processing is terminated, the CPU 66 advances the processing to step S23.

In step S23, the CPU 66 performs processing to judge whether the deal switch 24 has been activated. In this processing, the CPU 66 judges whether it has received a detection signal indicating activation of the deal switch 24. If not, the CPU 66 repeats step S23. If so, the CPU 66 advances the processing to step S24.

f. Internal Lottery Processing

In the abovementioned step S12 (FIG. 4), the internal lottery processing subroutine as shown in FIG. 6 is called.

In step S31, the CPU 66 performs processing for judging a game state. In this processing, the CPU 66 performs processing to judge the game state based on a game state flag stored in the RAM 70. When this processing is terminated, the CPU 66 advances the processing to step S32.

In step S32, the CPU 66 performs processing for setting a lottery table. In this processing, based on the game state as judged in step S31, the CPU 66 selects a lottery table in accordance with the game state from a plurality of kinds of tables having different winning probabilities stored in the ROM 68, and sets the selected table in the RAM 70. When this processing is terminated, the CPU 66 advances the processing to step S33.

In step S33, the CPU 66 performs processing for generating a random number. In this processing, the CPU 66 transmits an instruction for generating a random number to the random number generator 65. Upon receipt of the instruction, the random number generator 65 samples random numbers. The random numbers generated by the random number generator 65 are stored in the RAM 70 as random numbers indicating a lottery result. When this processing is terminated, the CPU 66 advances the processing to step S34.

In step S34, the CPU 66 performs processing for referring to a lottery table. In this processing, the CPU 66 refers to the lottery table set in step S32, and determines kinds of cards corresponding to the random numbers stored in the RAM 70 in step S33. The CPU 66 then stores the data of the kinds of the cards in the RAM 70. When this processing is terminated, the CPU 66 terminates the present subroutine.

In the above processing, ten cards are extracted from the cards of the deck usable in the game. Among the ten cards, five cards are initially displayed to the player, and the remaining five cards can be displayed to the player by card exchange. The initial five cards displayed to the player are invariably displayed on the first display 32. In contrast, among the five cards that are displayed by card exchange, only the desired cards are displayed on the first display 32 when the player desires the card exchange. In the present embodiment, the cards used for exchange are selected by lottery in advance, at the same time as the lottery of the cards initially displayed to the player. Alternatively, the determined number of cards may be selected by lottery after a card exchange number has been determined.

g. Processing for Displaying a Card

In the abovementioned step S14 (FIG. 4), a subroutine for displaying a card as shown in FIG. 7 is called.

In step S71, the CPU 66 performs processing to judge whether a game is in the high probability mode. If the CPU 66 finds a high-probability win game based on the value of a high-probability flag stored in the RAM 70 (namely, the value of the high-probability flag is 1), the CPU 66 advances the processing to step S73. Otherwise, (namely, the value of the high-probability flag is 0), the CPU 66 advances the processing to step S72.

In step S72, the CPU 66 performs processing for displaying a single deck. In this processing, the CPU 66 performs processing to display a five-card set of a single deck on the first display 32. More specifically, the CPU 66 supplies an instruction for displaying an image related to the kinds of the five cards to be initially distributed to the player from the cards, which are determined by the internal lottery and stored in the RAM 70, to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the corresponding image data, and stores the data in the video RAM within the display and input controller 200. In this way, the first display 32 displays the five cards initially distributed to the player. When this processing is terminated, the CPU 66 terminates the present subroutine.

In step S73, the CPU 66 performs processing for displaying multiple decks. In this processing, the CPU 66 performs processing to display a five-card set of a single deck on the first display 32 and, in accordance with the initial value stored in the RAM 70 indicating the number of decks initially shown in a high-probability win game, displays five-card sets of multiple decks on the second display 33. More specifically, the CPU 66 supplies the data related to the kinds of the five cards to be initially distributed to the player from the cards, which are determined by the internal lottery and stored in the RAM 70, as well as an instruction for displaying a card image to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the corresponding image data, and stores the data in the video RAM within the display and input controller 200. In this way, the first display 32 displays the five cards initially distributed to the player, and also the second display 33 displays a plurality of card sets initially distributed to the player. When this processing is terminated, the CPU 66 terminates the present subroutine.

h. Processing for Exchanging a Card

In the abovementioned step S14 (FIG. 4), a subroutine for exchanging a card as shown in FIG. 8 is called.

First, in step S71, the CPU 66 performs processing to judge whether a game is in the high probability mode (step S40). If the CPU 66 finds a high-probability win game based on the value of a high-probability flag stored in the RAM 70 (namely, the value of the high-probability flag is 1), the CPU 66 advances the processing to step S43. Otherwise, (namely, the value of the high-probability flag is 0), the CPU 66 advances the processing to step S41.

In step S41, the CPU 66 performs processing to judge whether any one of the hold switches 20 has been activated. In this processing, the CPU 66 judges whether it has received a detection signal indicating any one of the five hold switches 20 has been activated. If not, the CPU 66 advances the processing to step S47. If so, the CPU 66 advances the processing to step S42.

In step S42, the CPU 66 performs processing to hold the corresponding card. In this processing, the CPU 66 sets the card corresponding to the hold switch 20 activated in step S42 so as not to be exchanged, even after the deal switch 24 is activated. The CPU 66 also causes the first display 32 to display “HOLD” below the image of the corresponding card on the first display 32. When the hold of the corresponding card is terminated, the CPU 66 advances the processing to step S47.

In step S43, the CPU 66 performs processing to judge whether a designation of deck has been made. In this processing, the CPU 66 judges whether the player has designated a desired deck from a plurality of decks provided. If not, the CPU 66 advances the processing to step S43. If so, the CPU 66 advances the processing to step S44.

In step S44, the CPU 66 performs processing to judge whether any one of the hold switches 20 has been activated. In this processing, the CPU 66 judges whether it has received a detection signal indicating any one of the five hold switches 20 has been activated. If not, the CPU 66 advances the processing to step S46. If so, the CPU 66 advances the processing to step S45.

In step S45, the CPU 66 performs processing to hold the corresponding card. In this processing, the CPU 66 sets the card corresponding to the hold switch 20 activated in step S44 so as not to be exchanged, even after the deal switch 24 is activated. The CPU 66 also causes the first display 32 to display “HOLD” below the image of the corresponding card on the first display 32. When the hold of the corresponding card is terminated, the CPU 66 advances the processing to step S46.

In step S46, the CPU 66 performs processing to subtract a number of designated decks from a gaming condition counter value. In this processing, the CPU 66 subtracts a number of decks designated by a player from a value of the gaming condition counter. When the subtraction of a number of designated decks from a gaming condition counter value is terminated, the CPU 66 advances the processing to step S47.

In step S47, the CPU 66 performs processing to judge whether the deal switch 24 has been activated. In this processing, the CPU 66 judges whether it has received a detection signal indicating activation of the deal switch 24. If the CPU 66 determines not to have received, it advances the processing to step S40. If the CPU 66 determines to have received, it advances the processing to step S48.

In step S48, the CPU 66 performs processing to determine a card for exchange. In this processing, the CPU 66 determines the number of cards not being held, namely the number of cards the player desires for exchange, from the five cards selected by lottery in the abovementioned step S12 (FIG. 4) so as to be displayed to the player by card exchange. It may be alternatively possible that the CPU 66 determines cards to be exchanged by lottery from the five cards in the present step S44. Furthermore, it may be alternatively possible that the CPU 66 selects cards to be used for exchange from the five cards according to ranking, which the CPU 66 assigns to these five cards in the lottery in step 12 (FIG. 4). In some cases, the player may desire to exchange the five cards, namely all the cards in hand. When the determination of card exchange is terminated, the CPU 66 advances the processing to step S49.

In step S49, the CPU 66 performs processing for redisplaying a card. In this processing, the CPU 66 transmits the data of the kind of the exchanged card determined in step S34 to the display and input controller 200, which controls the first display 32 to display an image of the exchanged card in place of that not held in the five cards. The details of this processing are described later. When the processing for redisplaying a card is terminated, the CPU 66 terminates the present subroutine.

i. Processing for Redisplaying a Card

The processing for redisplaying a card called in step S49 (FIG. 8) is described below with reference to FIG. 9. More specifically, a description is provided of a case in which, for example: the cards of a “10 of Spades,” a “Jack of Spades,” a “Queen of Spades,” a “3 of Diamonds” and a “2 of Diamonds” are displayed first; the player selects the cards of the “10 of Spades,” the “Jack of Spades” and the “Queen of Spades” as hold cards; and a “Jack of Diamonds” and a “King of Spades” are determined by lottery as cards to be exchanged with the remaining two cards.

First, the CPU 66 retrieves a hand achieved by the combination of the held cards and the exchanged cards (step S51). Since this hand is fixed when the card exchange is terminated, it is referred to as an actual hand. Based on the combination of the held cards and the exchanged cards, the CPU 66 retrieves the hands stored in the ROM 68.

The poker hands such as Royal Flush and Straight Flush are stored in the ROM 68, along with the respective poker hand class data. More specifically, a poker hand class indicates the number of medals paid out in accordance with a card combination entitled to a predetermined award in the award table displayed on the first display 32 during the win game when the player bets a medal. For example, the hand class of Royal Flush is 500, the hand class of Straight Flush is 50, and the hand class of Four of a Kind is 20. In this case, a larger numeral value represents a higher hand class. Alternatively, the poker hand classes may be ordinal numbers such as “1,” “2,” and “3,” which represent the respective poker hand orders. The CPU 66 retrieves a possible highest poker hand stored in the ROM 68 for the combination of the newly displayed cards by exchange and the held cards. In the present embodiment, as the result of the card exchange, one pair of a “Jack of Spades” and a “Jack of Diamonds” is retrieved as an actual hand.

In the succeeding step S52, the CPU 66 retrieves a highest hand obtainable if one of the exchanged cards were another card, among the combination of the held cards and the exchanged cards. This hand is a hypothetical hand not actually achieved. Assuming that the “Jack of Diamonds” as one of the exchanged cards is another kind of card, the CPU 66 first retrieves a highest hand obtainable with the exchanged card and the held cards. More specifically, the CPU 66 retrieves the highest hand by exchanging the card of the “Jack of Diamonds” with other cards in sequence, and retrieving the corresponding hand for each of the changed cards. In the present embodiment, it is assumed that changing the “Jack of Diamonds” to the “Ace of Spades” results in a Royal Flush hand.

Subsequently, the CPU 66 retrieves a highest hand by changing the exchanged card of the “King of Spades” to other cards in sequence. In the present embodiment, changing of the “King of Spades” to the “Queen of Diamonds” results in a two pair hand of “Jacks” and “Queens.” Since the Royal Flush hand has a higher class than the Two Pair hand, the Royal Flush hand with the “Jack of Diamonds” as a target card can be retrieved as the highest hypothetical hand.

Next, the CPU 66 makes a comparison in classes between the actual hand obtained in step S51 and the hypothetical hand obtained in step S52 (step S53). If the class of the hypothetical hand is higher than the class of the actual hand, the CPU 66 advances the processing to step S55. If the class of the hypothetical hand is equal to or lower than the class of the actual hand, the CPU 66 advances the processing to step S54.

In step S54, the CPU 66 changes the display order based on the actual hand. For example, if the actual hand is a one pair hand of the “Jack of Spades” and the “Jack of Diamonds,” the “Jack of Diamonds” of the exchanged card is displayed first.

On the other hand, in step S55, the CPU 66 changes the display order based on the hypothetical hand. Specifically, the CPU 66 changes the display order such that the target card to complement the hypothetical hand is displayed last. In the present embodiment, since the target card for achieving the Royal Flush as the hypothetical hand is a “Jack of Diamonds” card, the display order is changed so that the last card to be displayed is the “Jack of Diamonds”.

In the succeeding step S56, the CPU 66 controls a display of the exchanged cards in accordance with the display order. Specifically, the CPU 66 first supplies an instruction for displaying an image of the first exchanged card to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the desired image data, and stores the data in the video RAM within the display and input controller 200. In this way, the first display 32 displays the exchanged cards. Subsequently, the CPU 66 performs delay processing for a predetermined time such as 0.2 seconds to 2 seconds, and transmits an instruction for displaying an image of the second exchanged card to the display and input controller 200, thereby causing the first display 32 to display the second exchanged card. Then, the CPU 66 causes the first display 32 to display the exchanged cards in sequence, with the delay processing in between.

By the successive display of the exchanged cards, for example, among the two exchanged cards facing down, the first one is turned face-up displaying the “King of Spades”. This enables the player to expect that a Royal Flush may be achieved when the other exchanged card not yet displayed is the “Ace of Spades”. In fact, the changed card of the “Jack of Diamonds” is then displayed, so that merely a one pair hand is achieved as an actual hand.

Thus, changing the order of displaying exchanged cards based on the hypothetical hand enables the player to keep expecting a certain hand to be achieved until the last exchanged card is displayed. After this processing, the CPU 66 terminates the present subroutine.

j. Processing for Judging a Result

The processing for judging a result called in step S14 (FIG. 4) is described with reference to FIG. 10.

In step S61, the CPU 66 performs processing to judge whether the game is in a high-probability mode. If judged so (the value of the high-probability flag is 1) based on the value of the high-probability flag stored in the RAM 70, the CPU 66 advances the processing to step S65. If not, the CPU advances the processing to step S62.

In step S62, the CPU 66 performs processing to judge whether the combination is a specified combination. If so (for example, Flush of Hearts or Diamonds), the CPU 66 advances the processing to step S63. If not, the CPU advances the processing to step S64.

In step S63, the CPU 66 performs processing for executing a special game. This processing is described later. When this processing is terminated, the CPU 66 advances the processing to step S64.

In step S64, the CPU 66 performs processing to judge a win game result. In this processing, when the CPU 66 determines that the win game result is worth receiving a number of medals, the CPU 66 controls the payout number to be stored in the RAM 70. When this processing is terminated, the CPU 66 terminates the present subroutine.

In step S65, the CPU 66 performs processing to judge a result of a high-probability win game. In this processing, when the CPU 66 determines that the high-probability game result is worth receiving a number of medals, the CPU 66 controls the payout number to be stored in the RAM 70. If a plurality of decks achieves a winning outcome, the CPU 66 stores the sum of awards thereof in the RAM 70. When this processing is terminated, the CPU 66 advances the processing to step S66.

It is to be understood that the abovementioned processing is exemplary of the invention and is not to be considered to be limiting. For example, if a plurality of decks achieves a winning outcome, CPU 66 may retrieve the highest poker hand and store an award corresponding to the highest poker hand in the RAM 70.

In step S66, the CPU 66 refers to a value of a gaming condition counter stored in the RAM 70. The CPU 66 provides an additional award in accordance with the value of the gaming condition counter (for example, the gaming condition counter value times 10 medals supplied). The value of the gaming condition counter is a subtraction of a number of decks, which has been specified by a player before a win with matching a specified combination, from a value set in accordance with a result of the special game described below (see step S86 in FIG. 11). In other words, the CPU 66 which performs processing of step S66 is an example of a controller, which supplies an award in accordance with a number of sets of cards before a winning outcome is achieved. When this processing is terminated, the CPU 66 terminates the present subroutine.

k. Processing for Executing a Special Game

Processing for executing a special game called in step S63 (FIG. 10) is described with reference to FIG. 11.

In step S81, the CPU 66 performs processing for executing a special game lottery. More specifically, the CPU 66 performs processing to sample random numbers and refer to the lottery tables stored in the ROM 68 so as to determine a deck number, etc. to be supplied in the special game. When this processing is terminated, the CPU 66 advances the processing to step S82.

In step S82, the CPU 66 performs processing for displaying an initial card. In this processing, the CPU 66 supplies an instruction for displaying images of the back faces of a plurality of cards to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the corresponding image data, and controls the data to be stored in the video RAM within the display and input controller 200. In this way, the second display 33 displays the back faces of cards initially distributed to the player in the special game. When this processing is terminated, the CPU 66 advances the processing to step S83.

In step S83, the CPU 66 performs processing to judge whether any operation has been made. In this processing, the CPU 66 judges whether the player has initiated a certain operation, receiving an input signal from the second display 33 in response to the player's touch operation on the touch panel of the second display 33. If so, the CPU 66 advances the processing to step 84. If not, the CPU 66 advances the processing to step 83. Even if the CPU 66 does not judge that an operation has been initiated, the CPU 66 advances the processing to step S84 after an elapse of a predetermined amount of time (for example, 10 seconds).

In step S84, the CPU 66 performs processing to judge whether it is the third card. In this processing, if the CPU determines that it is the third card turned over (by the player's touch operation on the second display 33), the CPU 66 advances the processing to step S85. If not, the CPU 66 advances the processing to step S87. The display and input controller 200 reads out the corresponding image data, and controls the data to be stored in the video RAM within the display and input controller 200. This enables the second display 33 to display the final result. When this processing is terminated, the CPU 66 advances the processing to step S86.

In step S84, the CPU 66 performs processing to set a gaming condition counter. In this processing, the CPU 66 sets an initial value indicating a number of decks initially displayed for the RAM 70, and causes the gaming condition counter to store the same value in accordance with a decision of a final result. When this processing is terminated, the CPU 66 terminates the present subroutine.

In step S87, the CPU 66 performs processing for displaying a result. In this processing, the CPU 66 transmits an instruction for displaying an image of a result (for example, the face-up cards, etc.) to the display and input controller 200 via the input/output bus 64 and the interface circuit group 72. The display and input controller 200 reads out the corresponding image data, and controls the data to be stored in the video RAM within the display and input controller 200. This enables the second display 33 to display the image of the result. When this processing is terminated, the CPU 66 advances the processing to step S83.

Thus, the CPU 66 is an example of a controller which executes the win game. In the win game, a card selected by a player from a plurality of cards distributed initially is exchanged with another card. The player wins a predetermined award if the cards distributed finally include a plurality of cards matching a specified combination. The CPU 66 is also an example of a controller that performs the high-probability win game, which increases the probability of winning in the next succeeding game when a combination of finally distributed cards matches a specified combination. In addition, the CPU 66 is an example of a controller that performs the game determining the gaming condition for the high-probability win game prior to a start thereof. The CPU 66 is also an example of a controller that initially provides in the high-probability win game a plurality of sets of cards in accordance with the gaming condition determined by the determination game. The CPU 66 is also an example of a controller that executes win games until a winning outcome is achieved. The CPU 66 is also an example of a controller which performs processing to display the executed win game in screens using images. The CPU 66 is also an example of a controller that controls the selection of sets of cards to execute a win game, in response to the operation of a select switch by the player.
